application ined .November 18, .1924. seria/1 jNo. 750,595,

This invent-ion'k aims to provide an improved separable fastener. Y I n the rawings, which illustrate two preferred forms of my inventi on Figure 1 is a front elevation ofthe fastener, show ing some of the underlying'po-rtions in dotted lines; l Y

Fig. 2`is ay section on the line 2--2 of Fi Q1; i I

3 includes a side and a rear elevation of the stud shown in Figs. land 2,; and

, Fig.` 1 is a section through the second preferred form of stud as it appears when se- 'curedto a support.

i 4Referring to the drawings, vI have shown 'a snap astjenerwhich includes a simple., durable and inexpensive stud which is particularly, though not exclusively, useful for co4 t operating with a socket to secure a carpet'to a metal floor board of an'auto'mobile or the like.

The stud illustrated comprises a socket-engaging cap member and yan attaching member for securing the l5 cap member to a suitable support. The cap member `is pressed from a single piece of metal and presents a head 1, presenting a peripheral bead, a central depression 2 in said head, a neck 3 and a flange portion 4. The attaching part comprises a tubular rivet portion 5 pressed from a single piece of metal and presents a cup-shaped portion 6 having a flange ortion presenting a depending outer peripheral wall 7 When the cap member and attaching part are secured together, the flange cup-shaped portion 6 ofl the attaching part is seated against the een# tral depressed portion 2 of the head and the flange portion 4 of the cap is crimped over the edge of the dependingwall 7 Thus, the rivet portion 5 of the attaching part extends beyond the cap member and is back-support pld by the central depressed portion 2 of the ead 1.

The stud support 8 may be` the sheet metal I side of an automobile or a sheet metal Hoor andthe stud may besecured thereto by the tubular rivet portion 5 which passes through an aperture in the metal support 8 and is then clenched against the innerv face of the support, as shown in Fig. 2. Thus I have provided a stud that is seated against the metal support and is back-supported by the attaching part so that it will withstand norin Figs. 1, 2 and 3 mal' pressures -exerted thereupon, especially whensecuredto metal fl'oers."

The socket which I have shown comprises a Acasing 11 containing a spring 12-for-engagement with the-Heek 3 of the stud. This s'e'xket' maybe secured to the socket-carrying meiilium 13 in any suitablemanner, but I pre-fer -to lsec-nre it thereto by an attaching rivet 14 secured to a cap 1 5' located at the opposite side of the carrying 'mediumv 13. 'The rivet .extends through the carrying Imedium through an aperture inthe socket casing andis then clenched against the casing, 'as illustrated in Fig. 2. llVlien the 'st-ud and socketv are engaged, the clenched over portion ofthe rivet 14 enters Ythe central depression -2 inthe cap of the stud.

Referring now to the second form of my invention illustrated l'in Fig.l 11, I have shown' a stud Whichfincludes a capkmember 16,--substantially as shown and described in connection with the first form of my invention, and an attaching part. The attaching part is provided with a cup-shaped portion 18 and a rivet portion 20, butin this instance the cup-shaped portion faces inthe opposite direction from that of' the first form. Thus the peripheral wall 21 extends toward the head of the stud, and passes between the depressed central portion 2 and the neck 3 of the cap member and seats against the head of the stud, and the flange 22 of the cap member isA clenched against the cup-shaped portion'18 of the attaching part to hold both parts of the stud in assembled relation. Attachment of the stud to the support is the same as described krelative to the first mentioned form of my invention.

`While I have shown and described two forms of my invention, it will be understood that I have done so for clarification merely, my invention beingV best defined in the fol lowing claims.

Claims:

1. A fastener stud comprising, in combination, a cap member havinga head, a' neck and a flange portion, a cooperating attaching member having a flange portion and Va wall portion projecting. from the outer periphery of the flange portion to provide a cup-shaped part, and an attaching part projecting from said cup-shaped part, one of said portions of the cup-shaped part cooperating with the head of the cap and the v other' portion Cooperating with the Hangeot' said cap to support said attaching part.

2 A fastener stnd comprising, in combination, a cap member having; a head, a neck and a flange portion, and a cooperating attaehing rivet normally` assembled with and carried by said cap member, said rivet pre sentinpV a cnp-shaped portion baol-s1ipported by a portion of said head and held in assembly with said cap member by said flange.

3. A fastener stud comprising, in combi nation, a` cap member having a head and a neck, a cooperating rivet presenting a onpshaped portion enclosed by said cap member and a tubular attaching portion extendingbeyond said cap member, said cap noember having a flange extending inwardly from saidneek to engage said cnp-shaped portion and secure said rivet and cap member as a unit prior to attachment of the rivet to a stud-Carrying support.

4. A fastener stud Comprising, in combination7 a cap member having' a head, a neck, and a flange portion, a cooperating attaelr ing part including a cup-shaped portion and a rivet portion, said enp-shaped portion heilig supported by the flange and head ol1 said cap member, the rivet portion extending beyond said cap member from the bottom of said cup-shaped portion to sec-nre said stud to a suitable stud support.

5. A fastener stud comprising, in eombr nation, a cap member having a head, a depression formed in said head, a peripheral Wall providingl the neck ot the stud and a cooperatingr attaching part normally assem bled with said cap member,` prior to attach ment to a suitable arrying medium, said at taching part comprisingr a cup-shaped portion having its outer peripheral Wall extend .ing` between the Wall providing the neel; of the stud and the Wall oit the depression, and having its tree edge seated against the inner surface oit' said head and a hollow rivet portion extending` troni said cap-shaped portion and back supported thereby when being upset to secure the stud to the carrying medinm.

t. A tastenerstnd comprising a cap-shaped portion presenting a head, a neck and a base portieri, said neck and said base portion being smaller in diameter than said head, and a rivet-presenting part normally assembled with said cap-shaped part prior to attachment to a stud support, the assembl)T beingI made by turning a portion of one part orer and against the other part, and the tree end of said rivet-presentinfci` part extending Atrom the base of said stud part, i

In testinion)v whereof, I have signed `my naine to this specification.
